SPECIFICATION forming partpof Y'Letters Patent N o. 611,191, datedSeptember 20, 1898. Application filed November-22, 1897. Serial No. 659,533. (No model.)

To all whom it may concern:

Be it known that I, GEORGE BALDWIN, a

citizen of the United States, residing Vat In of Indiana, have inventedcertain new and useful Improvements in Plows; and I do de'- clare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the figures of reference marked thereon, which form a part ofthis specification.

My invention relates to new and useful improvements in plows of theclass that have a means for regulating the depth of the furrow and forcarrying the weight of the plow upon a ground-wheel; and it consists inthe construction and arrangement of parts, as will be hereinafterdescribed, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective View of a plow embodying myimprovements, a part of the moldboard being broken away. Fig. 2 is asimilar View taken from the opposite side of the plow. Fig. 3 is a topvplan view. Fig. 4 is a detail view, partly in elevation and partly insection, showing the manner of adj ustably connecting the standard tothe plow-beam. Fig. 5 is a cross-section through the same on the line XX of Fig. 4. Fig. 6 is a longitudinal sectional View through themoldboard, landside, and cutter, taken on the line Y Y of Fig. 2. Fig. 7is a cross-sectional view through the draft-wheel of the plow. Fig. Sisan inner face view of the cap which fits on the outer end of the axle ofthe draft-wheel. Fig. 9 is a detail perspective View showing theconnection of the hand-lever of the draft-Wheel with the lower or maincasting. Fig. lOis a detail perspective view of the block which supportsor carries the bearin g-wheel casting, and Fig. 11 is a top plan view ofthe regulatingwheel upon the beam. The regulating-wheel is not shown inFigs. 2 and 3.

In detail l represents the draft-beam of the plow, and 2 the maincasting or upright of the same and to which the beam is adj ustablyattached, as shown in Figs.v 4 and 5, the upright having a slot 3 in itsupper end which opens into a recess 4 below, the slot and recess beingopen on one side of the upright plow-beam and on its upper end is lockedby the nut 6.

7 is the moldboard, which instead of being hollowed in the center isperfectly straight across at any point which is parallel with its lowerend.

8 is the landside, which is of the ordinary construction, and it and theshare are carried on the lower curved end of the upright 2, the landsideand the share being depressed sufficiently, as shownin Fig. 6, for thereception of a sod-cutter 9, thereby leaving the face of the sod-cutteriiush with the face of the share and landside. It will be noticed that apart of the recess is formed in the moldboard and a part in the side ofthelandside. The sod-cutter may be of any desired form or construction,that shown in the drawings being very simple in construction.

10 are the kplow-handles, one of which is atcached tothe inside of thelandside and the otherto the under side of the moldboard, the twohandles being connected near their outer ends by the cross-bar 11 andbelow by the cross-curved casting 12, which is slotted to receive thebolt 13, which passes through the inner end of the beamyl. Through thisand the bolt 6 the draft-beam can always be adjusted the same at onepoint as theother, as shown in dotted lines inFig. 3, and hence the plowcan be used with( either a' two or a three horse team without changingthe line of draft-that is, there will be no side draft at all. Y

15 is the draft or ground wheel, which supports the weight of the plow,taking the friction oif the landside, and this wheel is carried on thecasting 16, which is pivoted to the inside of the landside on the samebolt which on the landside.

31 is a block which fastens to the plowhandle and holds the draft-wheelhandle in a perpendicular position.

14 is a cross-brace to stiffen the plow and joins the moldboard andlandside. On the upper end of the casting 16 are formed recesses 17, oneon each side, and by means of these the handle 18, by which the groundor draft wheel is regulated, may be changed to carries and holds thelower end of the handle IOO suit the side adjustment of the draft-beam.The handle of the draft-wheelworks between the draft-beam and a curvedrack 19, secured on the side of the said beam, and by an inolosed springlocking-bolt 20 the draft or ground wheel may be set to regulate theplow for any desired depth. The locking-bolt 2O is operated by thehandle 21. I have shown in detail in Fig. 7 a very efficientconstruction to prevent dirt, &c., from entering the bearings of theland-wheel and draft-wheel, and it will be better understood byreference to that figure. The wheels 15 and 26 havea hub provided withannular grooves on each side and the caps 22 and 23, the first on theoutside of the axle which carries the land and ground wheels and thelatter being between the hub and the castings 16 and 25. Packing 24 isinterposed between the caps and the hubs, so that the oil used inlubrication will not be wasted, and at the same time the packingprevents dust and dirt from entering the bearing, this beingfurtherinsured by the connection of the caps with the hubs of the landand draft wheels. The landwheel 2G is mounted at the lower end of thecurved slotted arm 25, said arm having the integral brace 27, pivotall ybolted to the casting 2S. The casting 2S has the iange edges 29 toembrace the beam 1 and a bolt-opening to receive the bolt 30,said bolt30 passing through the slot in the curved arm 25, the casting 28, andthe beam 1 and secured by means of a nut at the opposite side of thebeam. By this means the depth of the furrow can be regulated easily andquickly.

It will be seen from the foregoing that this plow is very simple inconstruction, the adjustment of the draft-beam is perfect, theconstruction of the landside and moldboard are such as to obtain thebest results when in use, the insertion of the sod-cutter in a recessformed in the landside and moldboard insures a perfectly straightlandside, and by the construction of the land and ground wheels it isimpossible for any dust or dirt to enter the bearings of said wheels,and perfect lubrication is obtained.

I-Iavingfully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. In a plow, having a draft-beam mounted on suitable adj Listing-boltsat different poi nts,

whereby it can be adj usted at such points so as to retain its samedraft-line while being moved sidewise, the combination of the moldboard7, formed straight from edge to edge upon any line parallel with itslower edge, the landside 8, having the depression near its front end,the share, having the depression upon its side, and the sod-cutteradapted to lie within the depressions in said landside and share, withthe land-wheel 26, mounted upon the pivotal brace 27, and adjusted bymeans of the curved slotted arm 25, workin g in the casting 28, and thedraft-wheel 15, mounted upon a pivotal casting 16, and adj usted bymeans of a lever 18, having a spring locking-bolt 19, workin g in acurved rack-bar 20, all as shown and described.

2. In a plow, the combination of a draftbeam mounted on suitableadjusting-bolts at dierent points, whereby it can be adjusted at suchpoints so as to retain its same draftline while being moved sidewise, adraftwheel carried on the plow, and adjustable through a handle, saidhandle being adjustable to suit the adjustment of the draft-beam, and aland-wheel carried on the plow-beam, and adjustable through a slottedcurved arm, as shown and described.

` 3. In a plow, the draft and land wheels carried by suitable adjustingmeans, said wheels having hubs provided upon each side with annulargrooves, the close outer cap 22, having like grooves and ribs to fitagainst the outer face of said hub, the open inner guard or cap 23,adapted to fit against the inner face of said hub, said wheels and capsmounted upon the loose axle and having a space between eachrespectively, to receive the packing, as set forth.

4. In a plow, the landside and the share having a depression formed ineach, a sod-cutter fitting in said depression, flush with the face ofsaid landside and share, in combination with the moldboard formedperfectly straight across, from its front to its rear edge, on any lineparallel with its lower edge, as set forth.

In testimony whereof I affix mysignature in presence of two witnesses.

GEORGE BALDWIN.
